Wikkis:
I found a wonderful wikki to use within the classroom on the body systems and how different choices affect those systems (drugs, alcohol, etc.). I could definitely see students creating their own wikkis to learn from each other.

Podcasts:
When in iTunes I found various fitness podcasts that would be available for download. Students could use these in the classroom and as another thought, we could develop our own podcast for a particular unit. Team building is a unit I am trying to include character education and building responsibile learners into. We can demonstrate how these would be effective through a podcast.

Blogging:
I would love to see students blogging about their exercise outside of the classroom and how they were engaged in different activities as well as their experience. What a great place to get a helping hand from your peers to encourage you to do well in your pursuit of better health.
